I really like FCC, but there is a bug. I accidentally input wrong url, and project passed 
Please remove this bug, I want to earn my certificate 
There’s no way to check whether the URL you’ve passed is no the “wrong” URL since you can host your projects anywhere. It’s up to you to make sure you’ve submitted your projects correctly, otherwise your certificates can be invalidated later on.
Since I have submitted wrong url, I will resubmit when them. Thanks.
Its only hurting yourself too. If a employer ever checks then your in trouble.
This behaviour is different from before the update. Is this intended?
